Site hosting tons of email addresses

A little over a year ago I was doing a web search for my email address (something that's worth doing from time to time.) I ran across my name in a text file hosted at a domain called.....
http://www.freestuffengine.com/ There is a different site active at that domain now (although I don't know if it's owned by the same group, it may be....) Anyway, there were VERY large text files with (according to the file name) a million addresses. And YES... mine was in there.

my address was in a file called.... nima_1million_1of2.txt

Once I located this, I used wget to make a mirror of it on my hard drive as evidence and then complained (if I recall correctly) to the domain holder/hosting provider. I wanted to hold off posting here until I was certain it was down (for what I assume are obvious reasons.)

So, yes, there are gigantic lists of email addresses out there for sale...
